you are super kind, thank you so much! is this the only method to fullfil my dreams of an jailbroken kindle? or is there an alternative? ...

i dont think that i want to crack it open... jailbreaking an iphone was so ez :-((

Return the one you have and order a refurbished PW3 from Amazon.
Last I heard, they where still shipping with a version that can be jail broken.
And if not, return it under their "No questions asked" return policy.
